1. The oil press torque converter manufacturer ensures the flatness of the shaft and the facility exported from the medium and small low speed hydraulic motor, or chooses flexible connection.

2. The housing shall be filled with oil before operating the oil motor of the four-column hydraulic press. The housing should be filled with oil from beginning to end, and the internal structure of the fast hydraulic press gear motor is lubricated, otherwise it will destroy the brake pad hydraulic motor, make a big mistake!

3. Leakage connection: the leakage pipe of the hydraulic motor housing should be of full diameter as far as possible, and one-way throttle valve cannot be accepted. It should be connected to the oil tank from the leakage port immediately, so as to keep the housing full of oil. Leakage tube wire tube as far as possible to prevent siphoning phenomenon. The leaking pipe should end below the automobile fuel tank level display, and other pipes should not be connected to the leaking pipe. The leakage pipe of the motor of the four-column hydraulic press should be connected to the oil tank independently, not to the return street.

4. When the four-column hydraulic machine is connected to the oil pipeline, the sloshing hydraulic motor should ensure that the oil motor shell is filled with oil, so as to avoid the oil returning to the car tank when the oil is shut down. If the oil pipe is permeated up, the inner curve diagram of the hydraulic motor makes the oil hole discharged higher than the shell.
